Is Cancer the Biggest Killer in Australia? No—Cardiovascular Disease Is

Leading Causes of Death in Australia (AIHW / ABS Data)

Cardiovascular disease (CVD)—including coronary heart disease, stroke, heart failure—is the **#1 cause of death** in Australia, not cancer.

Ranking (Typical Year)

1. Cardiovascular Disease (~25–30% of deaths).
2. Cancer (all types) (~25–30%, very close second; sometimes #1 in specific age groups).
3. Dementia/Alzheimer's (rising, ~10–12%).
4. Respiratory Diseases (COPD, flu/pneumonia).
5. Diabetes, Accidents, Suicide.

Nuance

• Cancer is **#1 cause of premature death** (years of life lost).
• CVD deaths concentrated in older ages; cancer affects younger cohorts more.
• Both are largely preventable (smoking, diet, activity, screening).

Trends

CVD mortality declining (better treatment, prevention); cancer incidence rising (aging population) but mortality falling (screening, therapy). Dementia rising fast.
